Speculation has been swarming around Mariah Carey, since she's been rather coy about revealing the sex and due date of her baby.  Make that "babies".  People Magazine reports that Mariah and hubby Nick Cannon are indeed expecting twins.  Who was finally able to get her to come clean?  The president and first lady!

While performing at TNT's Christmas in Washington 2010 on Sunday, Carey ran into President Obama and First Lady Michelle Obama backstage. "They, ironically enough, questioned my wife about, you know, 'So, what are you having, are you having twins?' " Cannon said Thursday.

As a father of twins, I can predict that the next questions raised will be those concerning fertility.  I've found that people often assume that couples with multiples have had some sort of assistance from fertility drugs, and/or doctors.  Parents of multiples seem to be fair game, often fielding questions that would seemingly be taboo.

The couple has yet to reveal a due date.
